SSZipArchive versions 2.5.3 and older contain an arbitrary file write vulnerability due to lack of sanitization on paths which are symlinks. SSZipArchive will overwrite files on the filesystem when opening a malicious ZIP containing a symlink as the first item.
The product uses external input to construct a pathname that is intended to identify a file or directory that is located underneath a restricted parent directory, but the product does not properly neutralize special elements within the pathname that can cause the pathname to resolve to a location that is outside of the restricted directory.
The product attempts to access a file based on the filename, but it does not properly prevent that filename from identifying a link or shortcut that resolves to an unintended resource.
